ITOHN MAUITS SAHLIN, OF CHICAGO, ILLINOIS.

WIRE-CONNECTOR.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application f1ed February 11, 1907. Serial N o. 356,888.

To all whom it may concern.'

Be it known that I, JOHN li/IAURITS SAHLIN, a citizen oztl the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvenient in lVire-Connectors, of which the following is a specification.

This invention relates to wire connectors and more particularly to connectors for electric conductors, the object being to provide a connector so constructed that an absolutely perfect electric connection can be easily and quickly made without the use of soldering.

Another object of invention is to provide a pair of duplicate members adapted to be interlocked together and securely held in that position by bending the ends of the wires around one another.

lith these and other objects in view, the invention consists in the novel features of construction combination and arrangement of parts hereinafter fully described and pointed out in the claim.

In the drawing forming a part of this specification: Figure l is a plan view ot my improved connector showing the conuector secured thereon. Fig. 2 is a longitudinal sectional view ci? the connector showing the conductors arranged therein. Fig. 3 is a longitudinal sectional view of one ot' the members of the connector taken on line 3 3 ot Fig. 5. Fig. 4 is a longitudinal sectional view of the other member of the connector taken on line 4-4 of F ig. 6. Fig. 5 is a plan view of one of the members. Fig. 6 is a plan view partly in section oit' one or' the members. Fig. 7 is a section taken on line 7 7 of Fig. 2. Fig. S is a sectional view taken on line 8 8 of Fig. 2.

In the drawing A and B indicate the duplicate coupling members forming my improved connector which may be formed of any suitable metal such as iron or copper. The member' A consists of a tapering sleeve A having a half round opening, the thick side A2 formed thereby, being provided at its largest end with an outwardly projecting tapering pointed tongue A3. Spaced longitudinal grooves A4 are formed in the thick portion of the sleeve and the tongue forming a central rib A5. The member B is likewise formed of a tapering sleeve B', the thick side B2 of which is provided with a similar tongue B3 having spaced longitudinal grooves BAL formed in the face of the thick side and the tongue forming a central rib B5. The end ot the cables C and D to be connected are then passed through the members A and B and the pointed tongues of the members formed into the half-round openings of each other so as to bring the grooves of the tongues over the cables arranged in the grooves of the sleeves, and as the members are drawn together, the wires will be securely locked in the sleeves by the wedging action of the tongues, fornr ing a perfect electrical connection. r)The end C of the cable C is then twisted around the cable I) and the end D of the cable D around the cable C, so as to lock the sleeves together, thereby preventing any danger of the members being pulled apart.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is wire connector comprising duplicate members formed of tapering sleeves provided with seini-circular openings forming sides ot' ditl'erent thicknesses, tapering pointed tongues extending out from the thickest sides ot' said sleeves at their largest ends, spaced longitudinal grooves formed in the thick sides of said sleeves and said tongues, the tongue of each member fitting in the sleeve of the other member and wires arranged in the grooves of said members having one oi their ends twisted around the adjacent wire and bearing against the end of the respective sleeves.

JOHN MAURITS SAHLIN.
